3-Olaims. 1

The present invention relates generally new and useful improvements infishermens tools, and has for its .primary object to provide, in amanner as hereinafter set forth, a device of this character comprising anovel combination of a knife, fish sealer, gaff hook'and*welgh ingscale.

Another very important object of the invention islto provide acompound'tool of the'aforementioned character comprising novel means forlocking'the weighing scale against operation in the handle when it isdesired to use the knife blade.

Other objects of the invention are to provide a fishermans knife of thecharacter described which will be comparatively simple in construction,strong, durable, highly eificient and reliable in use, compact, light inweight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing,wherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in longitudinal section through a knife constructedin accordance with the present invention.

Figure 2 is a view in side elevation of the device, showing the tool inuse as a weighing scale.

Figure 3 is an end elevational view, lookin at the device from the line33 of Figure 1.

Figure 4 is a sectional view, taken substantially on the line 44 ofFigure 1.

Figure 5 is an elevational view, looking at the handle end of thedevice.

Figure 6 is a detail view in end elevation of the blade shank.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises atubular handle 8 of suitable material. Secured by a pin 9 in one endportion of the handle 8 is a bushing ID, the outer end portion of whichis internally threaded, as at l I.

The upper end portion of the handle 8 is counterbored, as at 12, andsecured by a pin l3 therein is an internally threaded socket M. Anopening l'5 in the socket I4, the purpose of which will be presently setforth, communicates with the socket bore.

Removably mounted on the handle 8' is a blade 16. The blade l6 includesa knife or smooth cutting edge [1, a toothed scaling edge l8, andterminates at "its 'free end in-a gaff hook l9.

"The'blade 16 is fixed on one end portionnf a "shaft or shank 20 whichis mounted dongl tudinally the bore 2| of the tubular handle 8 in spacedrelation to "the walls of said here. Immediately-adjacent the blade I 6,the shank :20 is provided with a threaded portion :22 which screws intothe portion H of the bushing 1.8. The shank 28 "further includes -athreaded fre end portion 23 which screws'into' the sockeizFill. It willthus be seen that the shank 20 is removably mounted in the bushing I 8and the socket I 4. Immediately adjacent the threaded end portion 23,the shank 20 has formed thereon a head 24 engageable in a seat 25provided therefor in the socket 14. The head 24 and the thread 23 arenotched, as at 26, to receive a locking pin 21 which is mounted on thefree end portion of a spring 28. The spring 28, in turn, is secured atone end on the lower end of the handle 8, as at 29. The opening IS inthe socket f4 accommodates the locking pin 21.

The coil spring 30 encircles the shank 20 in the bore 2| of the tubularhandle 8. The ends of the coil spring 30 are engaged with the bushing 10and the head 24. Communicating with the bore 2| is a longitudinal sightopening 3| in the handle 8 through which the shank 28 may be observed.Adjacent the longitudinal sides of the slot 3|, the handle 8 isgraduated, as at 32.

It is thought that the manner in which the device is used will bereadily apparent from a consideration of the foregoing. Briefly, thesmooth knife edge I! is used for cutting, the toothed edge I8 of theblade 16 is used for scaling fish and the hook I9 is used as a gaff. Forweighing a fish or other object, the device is held vertically with thehandle 8 uppermost, as seen in Figure 2 of the drawing. The spring 28 isflexed to disengage the pin 21 from the notches 26 for permitting theshank 28 to be unscrewed from the socket I 4 and the bushin 10. Whenthus unscrewed, the shank 20 i free to slide downwardly in the handle 8against the tension of the coil spring 30. The fish or other object tobe Weighed is then suspended in any suitable manner, as at 33, from thehook l8 and the spring 30 is compressed under the load. The head 24 onthe shank 20 may then be observed through the slot 3| and read againstthe graduations 32 for ascertaining the correct weight of the fish orother object.

It is believed that many advantages of a fishermans knife constructed inaccordance with the present invention will be readily understood andalthough a preferred embodiment of th device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction may be resorted to which will fall within the scope of theinvention as claimed.

Having described the invention, what claimed as new is:

1. A fishermans tool of the character described comprising an elongatedhandle having a longitudinal bore therethrough, a bushing and a socketin the bore, said handle further havin a. longitudinal slot thereincommunicating with the bore, a slidable shank in the handle threadedlymounted in the bushing and the socket for securing said shank againstsliding movement, and a blade on one end of the shank.

2. A fishermans tool comprising an elongated handle having alongitudinal bore therethrough, a bushing in one end portion of thebore, a socket in the other end portion of said bore, a shank slidablein the bushing and engageable in the socket, coacting thread on theshank, and in the bushing and the socket for releasably securing saidshank against slidin movement, av coil spring in the handle encirclingthe shank and operatively connected thereto for yieldingly resistingsliding movement thereof in one direction, a blade on one end of theshank, and means for securing the shank against rotation in the bushingand the Socket.

3. A flshermans tool comprising an elongated handle having alongitudinal bore therethrough, a bushing in one end portion of thebore, a socket in the other end portion of said bore, a shank slidablein the bushing and engageable in the socket, coacting threads on theshank and in the bushing and the socket for releasably securing saidshank against slidin movement, a coil spring in the handle encirclingthe shank and operatively connected thereto for yieldingly resistingsliding movement thereof in one direction, a blade on one end of theshank, and means for securing the shank against rotation in the bushingand the socket, said socket having an opening therein, said meansincluding a head on the shank having a notch therein, a spring mountedon the handle, and a pin on said spring operable in the opening andengageable in the notch for securing the shank against rotation.
